Nineteen nonionic surface active agents were tested for their inhibitory effects on tobacco mosaic virus (TMV) infection to Nicotiana tabacum L. cv. Xanthi-nc. The hydrophilic-lipophilic balance (HLB) values of the chemicals tested varied from 4.7 to 16.7, showing no significant relationship between inhibitory activities and HLB values. However, in the group of polyoxyethylene nonylphenol ethers with HLB values varying from 9.2 to 17.5 the inhibitory activity was the highest at HLB 13.7. Inhibitory activity of the chemicals depended also upon the structure of hydrophobic group, i. e., nonylphenol group was the most effective among alkylphenol groups, and lauryl was the most effective among alkylgroups. Polyoxyethylene nonylphenol ether, HLB 13.7, was the most effective among 19 chemicals tested. Examination on the action mechanism of polyoxyethylene nonylphenol ether, HLB 13.7, revealed that the chemical interferes with the attachment of the virus particles to infectible sites of the host and/or conversion of the infectible sites to infective centers.
